The systems of local exhaust ventilation of existing industrial enterprises, as a result of their construction elements imperfection, work with large air flow rate that causes considerable power and financial expenses. It is possible to increase efficiency of pollutants output hood, e.g. by set of its construction by circular air distinctor. A purpose of work is determination of distributing of the field of surplus pressure in the suction zone of cylinder hood with circular air distinctor and also optirnization of its diameter. Investigations of hood with circular air distinctor has been carried out on an experimental installation at isothermal conditions. The diameter of air distinctor a was varied within the limits of (0 -;- 2,0) diameter D of hood inlet chink. The analysis of the obtained epures of surplus pressure certifies: due to application circular air distinctor, which is located in plane of output apperture in the hood construction area of hood sucktion increases; zone of sucktion and vacuum value are maximum at attitude of diameter of air distinctor toward the diameter of hood inlet chink a/D = 1,75.
